The cross-session amnesia problem — the agent forgetting every design decision you made last week — is solved by persisting spacing grids, palettes, depth strategy and component patterns to a file the agent loads automatically.
A style dropper extracts a design's visual DNA — palette, typographic rhythm, spatial density — and transfers it onto another layout, so browsing for inspiration ends in exportable code or a prompt you hand to your coding agent.

AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
agent skill — A reusable instruction file that teaches an agent how to do one job well — the procedure, the tools, and what counts as done.
MCP — The Model Context Protocol — an open standard that lets any AI assistant plug into any tool or data source without custom integration code.
Why it matters
A three-layer system — design skills, agent canvases, taste development — for engineers to ship genuinely good UI without becoming designers. The missing method for everyone whose AI-built interfaces are functional but ugly.
Key quotes
“It catches the anti-patterns that make AI-generated UI look obviously AI-generated: overused fonts, gray-on-color text, pure blacks, nested cards.”
“The canvas is the shell; your agent is the kernel.”
“The first time I saw the agent swarm working visually on my canvas, it was mindblowing.”
“I spend about 20 minutes a day just scrolling through it. It's become part of how I warm up my eye before doing any design work.”
